Dairy product from European cow, say (4)

Ross

I believe the answer is:

edam

I'm a little stuck... Click here to teach me more about this clue!

'dairy product' is the definition.
(Edam is an example)

'european cow say' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'cow say' becomes 'dam' (I can't explain this - if you can you should give a lot more credence to this answer).
'e'+'dam'='EDAM'

'from' is the link.

Can you help me to learn more?

(Other definitions for edam that I've seen before include "Sphere of Dutch cheese" , "Made into popular cheese" , "Yellow cheese with a red covering" , "Round, yellow cheese" , "Cheese made in Holland" .)

I've seen this clue in The Telegraph.
